Gamma-poly-glutamic acid (γ-PGA) is a natural occurring, multi-functional, and biodegradable biopolymer. It is produced through fermentation by Bacillus subtilis using glutamic acid. PGA is consists of glutamic acid monomers cross
molecular weight of PGA is usually between 100~1000 kDa. It is water-soluble, edible and non-toxic towards human, and is environment friendly. It has broad applications in the fields of medicine, food, cosmetics, and water treatment.
Applications
γ-PGA and its derivatives can be widely used in the food industry, cosmetics, health care, water treatment, hygienic products, medical and other fields.
